HTTP protocol, attached file?

Question

Programming

I can't figure out why Chrome highlights the file download request: The

headers are:
Connection:close
Content-Disposition:attachment; filename="Red.mp3"
Content-Length:5949316
Content-MD5:1640cccf73d07d75c4e2722519af028b
Content-Type:binary/octet-stream

The file is downloaded, the hash matches, but what is trying say chrome?

Answer 1

As I understand it, what is marked in red is what cannot be put into the cache.

Answer 2

he writes - the download is interrupted. Maybe Content-Length is not correct?
